finite normalized tight frames are interesting because they provide decompositionsin applications and some physical interpretations. in this article,we give a recursive method for constructing them.

members of the 67th world health assembly in 2014 were presented with a framework document to guide world health organization (who) engagement with non-state actors, a key part of who reform kick-started in 2011. according to this document, non-state actors include four distinct constituencies: i) nongovernmental organizations (ngos), ii) private sector entities; iii) philanthropic foundations;...

global health research is essentially a normative undertaking: we use it to propose policies that ought to be implemented. to arrive at a normative conclusion in a logical way requires at least one normative premise, one that cannot be derived from empirical evidence alone. but there is no widely accepted normative premise for global health, and the actors with the power to set policies may use...

The WHO's new End TB Strategy 2016-2035 has evolved from previous global strategies to respond to old and new challenges and take advantage of new opportunities. It frames the global fight against TB as a development, social justice and human rights issue, while re-emphasizing the public health and clinical fundaments of TB care and prevention. In this commentary, we outline how TB prevention, ...

Gorik Ooms recently made a strong case for considering the centrality of normative premises to analyzing and understanding the underappreciated importance of the nexus of politics, power and process in global health. This critical commentary raises serious questions for the practice and study of global health and global health governance. First and foremost, this commentary underlines the impor...

Global motion compensation (GMC) removes the impact of camera motion and creates a video in which the background appears static over the progression of time. Various vision problems, such as human activity recognition, background reconstruction, and multi-object tracking can benefit from GMC. Existing GMC algorithms rely on sequentially processing consecutive frames, by estimating the transform...

The formulation of global health policy is political; and all institutions operating in the global health landscape are political. This is because policies and institutions inevitably represent certain values, reflect particular ideologies, and preferentially serve some interests over others. This may be expressed explicitly and consciously; or implicitly and unconsciously. But it’s important t...

This article introduces a new representation of surface global parametrization based on Cartan’s method moving frames . We show that system structure equations , characterizing the local coordinates changes with respect to frame system, completely characterizes set possible cone parametrizations. The discretization this provably provides necessary and sufficient conditions for existence valid m...
